Retail giant Wal-Mart Stores may set up a back-office center in India's technology hub of Bangalore to cater to its multiple functions across the world, the Economic Times said on Friday, citing unidentified sources.

Wal-Mart, which has tie-ups with Indian outsourcers such as Infosys Technologies, is expanding its IT resources globally, including in India, but it has no plans to build a back-office on its own, a spokesperson told the newspaper.
